Just get the club auger and auger out a nearer spot that is still visible for motorists and is in a safe spot, and go to town. When done, dig up the signpost and transplant into new hole, add one bag of Quikrete if needed, and you are golden. Little back muscle and a little time, nothing to it!

Life is short, make the most of every opportunity you get to do the right thing, even when it would be easier to just say "Screw it, I don't care." Make a difference, one opportunity at a time. Smile!
